T 0 all whom it may concern:

Be it known that 1, JOHN Hnrssnnnnnenn, a citizen of the United States,and a resident of New York, in the county of New York and State of "NewYork, have invented certain new and useful Combination Knives withSharpeners, of which the following is a specification.

My invention relates to improvements in cutlery, and particularly topocket knives, the object of the invention being to provide a detachablesharpening medium which may readily be incorporated in the handle of atool, so that at any time the tool may easily be sharpened with facilityand Without loss of time. a

Another object of the invention, is to provide such a sharpening mediumwhich may belcarried in the tool handle without rendering the sameofinconvenientor bulky size, or awkward for use, will not weaken thestructureof the handle, and will be a valu able adjunct to the tool.

With the above, objects in view, my invention consists in pivoting oneof the handles or gri s of the tool to the frame or body of the toolire/mounting a removable whetstone or sharpening medium in such handle,

and in providing means-for lockingthe free end of the handl'e'to theframe; and the invention comprises certain other novel-features ofconstruction, combination and arrangement of parts substantially asherein In the accompanying drawings: Figure 1, IS a side elevatmn of anordinary pocket knife equip ed with my improvements, one" of the hand esor grips being swungopen to show the sharpening medium therein. Fig.

2, is a front edge view of the same. Fig. 3,

is a transverse sectional View of the knife on line a?; of Fig. 1. Fig.4, is a broken deta1l viewof a portion at oneend of the knife, to

show the springjcatch for securing the handie in closed osition. 'Fig.5, is a trans verse section'a view of one of thehandle members with animproved form of sharp? ener therein.

The knife illustrated the accompanying drawings is. of the usualpattern, having the.

rigid face plate A and the pivoted face plate B, forming the handle andalso hav ng-the pair of side plates 9 and 10, form1ng the frame, and theblades D and. E, pivotedtherebetween. Tips- 3 and F are secured to theside plates atone end, one of the tips (C) having beveled or undercutedges 3, and the other tip (F) having its inncredge also beveled, asshown at 8, the two tips forming what is known as the head of the knife.A rivet pin 11, passes through the side plates at the front edge andserves to secure the blade actuating spring H therebetwcen. Passingthrough the side plates'at the end opposite the head, is a pivot pin.22, to which is pivotally secured the casing or handle member 13, theopposite or free end of said handle member being beveled at an inclineto engage the undercut portion of the head. Within said casing isarranged a sl' arpeuer 6, and such s arpener maybe of stone, metal,mineral composition or any other suitable abrading material. Struck upfrom the side plate 9, near he end at the head of the knife, is a springtongue 12, having a lip 13, adapted for engagement with the recess inthe handle when the handle is closed. other grip or handle member is nothollow like the one just described, but has a strip of sharpeningmaterial 4, secured to its lower face. This handle portion has a bevelededge to engage the undercut head at one end, and in' its opposite end isformed a hole or socket 1 to form a bearing for the head of the rivetorpin 2, and thereby lock the handle in place.- A notch 5, is formed inthe lower edge at the end of said handle sothat the same may be readilyremoved. The handle iece B, on its inner face and near its free end 18formed with the lug or stop let, which holds the file in properposition. v

In the sectional view, Fig. .5, I have shownan improved form ofsharpening medium, which comprises a metallic reinforcing strip 6,having a layer of abrasive material 6 and 6 secured to each facethereof. This sharpener is especially valuable when used in connectionwith a knife, as it is light'and cpmpact, and .may provide both fine,and. coarse abrading surface. The sharpener 4 maybe readily employed forsharpening the blades of other knlvos when required.

I do not wish tolimit myself to the appli-- cation of a sharpener to aknife only, as the device may as well be a plied to otherarticles'OfcutIer-y, and dit'erent materials for theisharpening mediumlnay be employed.

From the foregoing description taken in connection with the drawings, itis evident that l have accomplished all theobjects the undercut tip, theopposite sidebeingin ed to the end of the form of a hollow casing toform a receptacle, said hollow casing being pivotally secured to theknife and having a beveled end to engage beneath- 'the undercut tip. I

2. A pocket knife having beveled undercut tips, sides to the knife, oneof said sides being reinovably secured to the knife and having aninclined end to interlock with the undercut tip, the opposite side beinghollow toform a receptacle, said hollow side pivotthe knife and having abev' eled end to engage beneath the undercut tip, and a s ring catchupstanding from the body of the knife to engage and hold the hollow sideclosed.

3. A pocket knife substantially-as shown to engage beneath .anddescribed having end pieces provided with beveled undercut tips, sidesforming the handle to the knife, said sides havin bev-' eled inclinedends for cooperation wit 'said' of said sides being hollow, and said.hollowsidebeing mounted to be swung open tips, one
